“…The authors feel that some additions in the metadata parameters of the source file would result in precise extraction and analysis of authentic digital evidences. Gopalakrishnan, A., Vineti, E., Mohan, et al, (2018) proposed a model for maintaining the integrity of evidence by heterogeneous piecewise hashing and also issuing a digital certificate named as Digital Evidence Integrity Certificate (DEIC) for evidence files. The authors wish to extend the DEIC model to add the attributes like owners public key, issuer public key, the hash algorithm used with precise version and hash of the whole file including DEIC be a part of the information that can be extracted from the metadata for verification and analysis of digital artifacts.…”
